获取系统硬件信息
来源：互联网 发布：南方数据粘贴 编辑：程序博客网 时间：2024/05/16 15:08
由于项目需要，要求做一个服务器的实时性能监控（CPU、内存、网络利用率等）和读取服务器的硬件配置参数的接口供项目组使用，就是一个类似于鲁大师之类的东东吧...
下面是我们利用WMI编程经常要用到的WMI内置提供程序清单，以供编程参考。
1.Active Directory提供程序
链接库文件：dsprov.dll
命名空间：rootdirectoryldap
作用：将Active Directory 对象映射到 WMI。
2.事件日志提供程序
链接库文件：ntevt.dll
命名空间：rootcimv2
作用：管理 Windows 事件日志，例如，读取、备份、清除、复制、删除、监视、重命名、压缩、解压缩和更改事件日志设置。
3.注册表提供程序
链接库文件：stdprov.dll
命名空间：rootdefault
作用：读取、写入、枚举、监视、创建、删除注册表项和值。
4.Win32 提供程序
链接库文件：cimwin32.dll
命名空间：rootcimv2
作用：提供关于计算机、磁盘、外围设备、文件、文件夹、文件系统、网络组件、操作系统、打印机、进程、安全性、服务、共享、SAM 用户及组，以及更多资源的信息。
5.Windows 安装程序提供程序
链接库文件：msiprov.dll
命名空间：rootcimv2
作用：提供对已安装软件信息的访问。
好，废话到此为止,还有不懂的自己下去慢慢研究：现在看代码...
一、基于API方式的实现代码，简单的对部分API函数的封装：

二、通过WMI（windows管理规范）接口编程来实现系统硬件信息的获取~~这个相较于上面API方式就方便多了~~~使用起来是相当的方面~~~但是....但是.....这个他妈的实在是太慢了~~~~~比上面的API方式要慢很多倍~~~我没有试过WMI在.net平台下的效果，但至少在MFC工程里面是相当的慢，看代码~~

上面就是一个WMI的封装，返回参数均以CString类型返回调用顺序：
1.实例化一个CWmiInfo类对象
2.调用InitWmi()函数初始化COM组件等。。。函数中有说明必须调用InitWmi初始化WMI组件，否则所有调用都无意义。
3.调用GetXXX方法获取你要获取的字段值。
4.最后使用完CWmiInfo类对象之后一定要记得调用ReleaseWmi()函数来释放资源
调用说明:
WMI的字段类名好像都是以Win32_开头。。。。如：Win32_Processor，Win32_PhysicalMemory等等。。。所以，你只要在MSDN输入Win32_就会看到很多以WMI结尾的类了。。。剩下的就是你的English水平问题了，这里google也可以帮你，如果你需要的话。
